ADA-128

Modular High-Quality Audio Conversion System

A new breed of audio converter has arrived: Prism Sound’s Dream ADA-128.

The Dream ADA-128 redefines flexibility, capacity, and performance standards in professional audio conversion.  In creating it, we ripped up the rule book and started again, using all our 30+ years of ADC and DAC development experience.  Building on the legacy of the Prism Sound Dream ADA-8XR, the resulting Dream ADA-128 architecture is so capable that it is set to meet the needs of the most demanding facilities for years to come.

The Dream ADA-128 is a 2U chassis that can accommodate up to 20 plug-in Modules.  These presently include eight-channel analogue input and output Modules and an eight-channel AES3 Module.  Four of the slots can accommodate a range of 64-channel Host Modules which include Pro Tools HDX and Dante Host Modules (and more to come).  As well as being able to route analogue and AES3 I/O to and from Host media, full routing flexibility allows analogue to/from AES3 routing without use of Host slots, and Host-to-Host bridging.

The Dream ADA-128 contains four independent clock generators, each of which can run at different sample rates and with different sync sources.  The ADA-128’s Host and I/O Modules can be dynamically assigned to these Clock Domains, allowing multiple workflows (such as separate project studios or ingest stations) to simultaneously share the resources of a single ADA-128’s resources.

Every I/O Module, as well as the unit’s built-in Routing Module, have dedicated DSP capability, which will allow a wide range of future functionality to be added by a simple software download.

The Dream ADA-128 incorporates Prism Sound’s unique Verifile technology, wherein every ADC in the system can add imperceptible metadata to its dither signal, allowing downstream processes to check that every sample in a stream is exactly as it left the ADC.  This reduces the need for expensive and unreliable listening tests of every minute of every digital recording or transmission.

These and many other unique capabilities make the Dream ADA-128 the only box you will ever need, no matter what your application.

A versatile store system allows swift reconfiguration of all or part of the unit (including individual Clock Domain resources).

The Dream ADA-128 can also be remotely controlled by other equipment in the system, for example by Dante or Pro Tools Hosts, or by dedicated controllers.

Eucon integration is currently in development.

Verifile Software

VERIFILE

Verifile is a radical new proprietary technology exclusive to Prism Sound which allows computer audio streams and recorded files to be quickly checked for a wide range of clicks, errors and dropouts, without any compromise in the audio content or any additional metadata. The Verifile process is entirely invisible and inaudible to the user, so using it is simplicity itself.

Developed to meet the needs of our audio archiving clients where even the most minute, inaudible error is completely unacceptable. Verifile can quickly identify and detect any such imperfection making it also the ideal choice for mastering & mix engineers.
